TAMPA, Florida (WFLA) — Humans have come a long way since the days of caveman, but a new diet is looking to the past for healthier inspiration.

It’s called the Paleo Diet, or the caveman diet.

The idea is that people should eat only what our ancestors would have been able to hunt and gather.

Seeds, nuts, fruits and vegetables are on the menu, and those who follow the diet believe that those are foods that our bodies are best evolved to process.

Jordann Windschauer first tried the paleo diet last fall.

“I did it for a month. It was a 30-day challenge,” she explained. “I ended up losing five inches, and then we did it for a second month and I lost five more inches.”

Windschauer said eating the paleo way gives her more energy. But she found she missed sweets and baked goods. So, she figured out how to make them for herself, and has launched a businesses called The Paleo Box.

“We’ve spent many months researching every ingredient to make sure it does follow exactly the paleo guidelines,” she said.

Windschauer now bakes muffins, cookies, breads and granola and sells them online. She takes orders and delivers the products herself. She even makes her own almond butter and almond flour for her products.

“It’s based off the chemical make up of the human body,” she said. “It’s basically what we need to survive.”

She’s only been in business for four months, but Windschauer is already considering expanding to a commercial kitchen.

“Everyone’s hearing about it, and trying it and sharing it. The interest level in general is going up,” she said.
